. <br /> The highes� rated community was the Shallow Marsh community rated at 0.1. Averaging all the communities <br /> together, the Vegetative Diversity and tntegrity of this wetland is Low. A more accurate look uses a weighted <br /> average; u�ing this method, this site shows a Low Vegetative Diversity and Integrity. <br /> The majorifiy of vegetation at this site, such as it is, does not contribute to wetland function beyond water <br /> retention and flow resistance. However, because the weighted average can "hide" smaller communities, <br /> `always check for even small patches of high-quality species. <br /> Functional Ratinas <br /> Function Rating Comment <br /> �Vegetative Diversity Low If vegetation is present, the primary communities are compromised by <br /> extensive invasive and/or non-native species. Ongoing maintenance will <br /> be necessary to restore native ecologic communities, although the <br /> presence of invasives upstream will limit the success of restoration <br /> efforts. <br /> Additional stormwater Moderate Sediment removal would improve the ability of this site to maintain water <br /> treatment needs quality. <br /> Maintenance of High Due either to careful human management or lack of alteration of the <br /> Hydrologic Ftegime outlet or watershed conditions, the wetland maintains a hydrologic <br /> regime similar to the original wetland type. This stability supports <br /> characteristic vegetative communities and is closely associated with <br /> flood attenuation, water quality, and groundwater interaction. <br /> �lood/Stormwater/Att Moderate The wetland provides some flood storage and/or flood wave <br /> enuation attenuation. It may have either an altered or unrestricted outlet, <br /> disturbed wetland soils, thin or little emergent vegetation (with channels) <br /> or it may be situated high in a watershed with a low proportion of <br /> impervious surfaces, moderate runoff volumes, loamy upland soils, and <br /> one or more other wetlands present within the subwatershed. <br /> Downstream Water Moderate This wetland has some ability and opportunity to protect downstream <br /> Quality resources. The ability of the wetland to remove sediment from <br /> stormwater is determined by emergent vegetation and overland flow <br /> characteristics. A high nutrient removal rating indicates dense <br /> vegetation and sheet flow to maximize nutrient uptake and residence <br /> time within the wetland. The opportunity for a wetland to protect a <br /> valuable water resource diminishes with distance from the wetland so <br /> � wetlands with valuable waters within 0.5 miles downstream have the <br /> greatest opportunity to provide protection, as do those that receive more <br /> (and less-treated) runoff. <br /> Maintenance of Moderate Wetland water quality is average. Sediment removal from incoming <br /> Wetland Water water would benefit the site. Also consider reducing the amount of <br /> Quality stormwater directed at the site. Sustaining a diverse wetland may <br /> require additional control over upland land use and the buffer. <br /> Shoreline Prptection Not The site does not fringe a deepwater habitat, lake, or is not within any <br /> Applicable type of watercourse. <br /> Page 2 of 4 <br />
